KNUCKLE-JOINT.

Specification of Letters Patent. Application filed January 30,

I Patented Nov. 27, 1906. 1906. Serial No 298,712.

Be it known that I, \VILuAu Cnu'ronLow, a citizen of the United States, residing in Paterson, county of Passaic, State of i\'ew Jersey, have invented certain new and useful Improvements in Knuckle-Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to flexible connections, known in the art as knuckle-joints, between the actuating-levers for jacquardmachines and the cranks from which said levers are moved. These devices ordinarily comprise in the more recent development of the art three members pivotally connected together in such manner that the end members stand in intersecting planes, the parts which form the pivots being separable or detachable. Y

My invention is an improvement on the uckle-joint disclosed in myUnited States Letters Patent No. 797,267, and has for its object to make the pivot parts therein reauto'matical y maintain parts constantly lubricated.

the accom anying drawings, Figure 1 is a side view of one form of my improved uckle-jointh Fig. 2 is 'a view, partly in ont elevation and artly in vertical central section, of the knuc e-joint seen in Fig. 1; and Figs. 3 and 4 are side and front views of part of the knuckleolnt.

a represents a jacquard-lever, and b the loop ortion fitted onto said lever and adjusta lysecured thereto by a set-screw c of members of the knuckle-pint. d is the'forked or'bifurcated portion 0 said her, the same being; as shown, inthe form of. two. spaced-disks standing parallel to each other.

e is a rod which may be connected with a suitable rotatin crank" of the, loom and d ,into the tubular pielrtion f of the other end member of the ucklejoint, said other end member also having a forked portion 9 like the forked portion d of the first-mentioned end member.

i is the intermediate or connecting memher, the same comprising a short neck 7' and two thick disks It, arranged at right angles to each other and disposed in the forked portions of the end members.

'1 is a cylindrical shell of relatively large diameter which penetrates the disks of and It on the one hand and the disks 9 and It on the other, serving as the pivot part in each instance. .lhis shell may be kept in place by one or more set-screws 1n, preferably mounted in enlargements n and 0, respectively, of the disks d and g.

It is preferred that the device be self-lubricating. To this end the shell l is in each instance provided with one or more orifices p, opening into the bore of the disk la, and said shell contains an absorbent holder g for oil or other lubricant. The lubricant-holder y may be kept in place in the shell by two plugs r, set in the ends of the shell and held against outward displacement by a bolt 1",

avmg a wing-nut s.

In the modified form of the end member of the knuckle-joint which is directly carried by the lever a, instead of the set-screw c being set in the top of the loo '1) the latter is formed with a lug t, adapte to stand opposite the under side of the lever a and reinforced by integral webs '11,, and in this lug the setscrew is mounted. renders the set-screw more accessible in ad justing. Preferably, as shown, the parts 25 and u are duplicated and-a set-screw 0 arranged in each lu t.

aving thus in ly described my invention, what I claim as new, and desire to secure by Letters Patent, isk 1. In a knuckle-joint,th'e combination of two substantially similar end members disposed in intersecting planes and each having a forked portion, an intermediate member having its extremities received by the forked portions of said end members, each of said orked portions and the art of said intermediate member received ti iereby having alined openings of relatively large diameter, and relativel thin-walled c lindrical shells each arrange in a set of said alined openings and forming the bearing between said intermeiate member and the corresponding end member, each shell snugly fitting said openingsfsnbstantially as described.

aknuckle-joint, the combination TlllS constructiontwo substantially similar end members disposed in intersecting planes and each having a forked portion, an intermediate member having its extremities received by the forked portions of said end members each of said forked portions and the part of said intermediate member received thereby having alined openings of relatively large diameter, relatively thin-Walled cylindrical shells each arranged in a set of said-alined openings and forming the bearing between said intermediate "member and the corresponding end member, each shell snugly fitting said openings and having a lubricant-orifice, and a lubricant-holder contained in each she'll, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of January, 1906.

WILLIAM ORUTOHLOW.
